Depending on the type of Mercedes-Benz you drive, there can be different parts that are included with the internal combustion engine that are important to take care of. A part that is important to take care of if your vehicle has it would be a the rocker arms. Rocker arms are located in between your pushrod and intake valves in the combustion engine. They are used to help open and close the exhaust and intake valves of the combustion chamber. The rocker arms are important parts that ensure these valves work properly and keep the performance of your engine high. There are some signs you can look out for that might indicate your rocker arms are wearing down. If you hear ticking or clicking noises when you start your engine, you should check the rocker arms while the engine is still running. You might see there is wear and tear or damage on them.
